IMPROVEMENT IN ORE CONCENTRATORS AND WASHERS.

Specification forming part of Letters Patent No. 149,622, dated April14, 1874 applicationfiled December 23, 1873.

To all whom. it may concern:

Be it known that I, J. B. WILDER, of Sonora, Tuolumne county, State ofCalifornia, have invented an Improved Concentrator; and I do herebydeclare the following description and accompanying drawings aresufficient to enable any person skilled in the art or science to whichit most nearly appertains to make and use my said invention orimprovement without further invention or experiment.

My invention relates to an improved table or sluice section forconcentrating the heavy portions of pulp or pulverized ore by the wetprocess.

My improvement consists in mounting the table or sluice section uponsprings, and then Vimparting to it a forward and side motion by acam, sothat when it is released from the cam the springs will force it backagainst twoK abutments, by which a compound jar will `result. Theseabutments are so arranged that the direction of hthe combined concussionwill be in a line diagonally across both the face of the table andthecourse of the moving` pulp, so that the sulphurets and heavyparticlesof metal will be forced in a line with the line of concussion, while thelighter portions are carried off by the water. l

In order to more fully illustr.y te and eX- plaiu 1ny invention,referenceis ad to the drawings accompanying this speciiication, inwhich- Figurel is a perspective view of my invention. Fig. 2 is a sideview near one end. Fig. 3 is an end view.

A represents a table or sluice section, which is mounted upon theC-springs B B. One of these springs,B, supports the rear end of the Ytable, while the other, B, supports one corner ofthe forward end, asshown. An ordinary spring-leg, b, supports the opposite forward corner.rlhe table has side boards c, in the manner of constructing an ordinarysluice. A post, 1),'i's secured to the base or foundation timberd on theside of the table oppo site the sprigiS B', while another post, F, issecured at i `rear end. A shaft, g, passes through the ppst D, andcarries, at its inner end, and direcly below the table, a double cam, h,The ms of this cam are made bev while the side bevel forces it to oneside.`

Abutting points j j are secured to the posts vE D, so that when thetable is released from the cam the springs will drive it back againstthem simultaneously, and thus give a compound jar or thump to the table.As will be readily seen, the concussion produced by this compound jarwill be in a line diagonal to the length of the table, the angle ofconcussion becoming greater toward the rear end of the table. Across theface of the table I make two or more inclined channels, K K, the shallowportion being at the discharge side of the table. An opening through theside of the trough, at the lower end of each channel, permits the waterand lighter portions to escape, while a similar opening through theopposite side allows the sulphurets to pass out into a pan, Z, fromwhich they will be conveyed by a pipe, m, to any receptacle prepared forthem. The concentratingtable can be set at any desired angle. The pulpis fed upon the upper end of the table, and flowing down it is arrestedby the channels K K. The compound jar then causes the sulphurets andheavy portions of the pulp to travel up the channels into thedischarging pan and spout, while the water will carry off the gangue andlighter portions through the opposite side.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s-

The concentrating table or sluice section A, provided with inclineddiagonal grooves or channels K K, and mounted upon springsB B l, incombination with the double inclined cam h and abutments j j,substantially as and for the purpose above described.

In witness whereof I hereunto set my hand and seal.
